The frame 13 is pierced at 15, to allow the tree passage of the liquid about the float. The upper compartment is provided with a stopcock 3 to permit the escape of air. Normally it is kept open. 7

C is a bed-plate on which are placed the several rows of bottles to be filled. it is constructed of a solid plate of glass or vul canite-if of glass, preferably of the variety known as iloonglass anc ground on its upper surface. A framework 29 of: any suitable construction supports the lc bars 21 which latter support the bed A One flange of each of the angle bars 21 projects under the lo ver side of the plate and the other flange thereof protects the outer edge. Bars shown in elevation at 24-.24, rest on the side edges of the bed-plate C. Gaskets 23 are provided for the purpose of cushioning the plate. The cars are held firmly to the bed-plate by clamps 2727 screwed to the angle irons 21-21 and to the bars 2 l-24; and projecting over its upper surface. hese clamps, of which h used on each side, are used as supports for side guides for bottles whe e guid s are used.
